SNMPTrapMgr Class

Properties Methods Events Config Settings Errors

The SNMPTrapMgr class provides a UDP-based listening point for SNMP traps.

Syntax

SNMPTrapMgr

Remarks

The SNMPTrapMgr class provides a UDP-based listening point for SNMP traps and informs as specified by the SNMP RFCs. The class supports v1, v2c, and v3 traps.

SNMP over DTLS is also supported when SSLEnabled is set to True. The SSLCert properties are used to select a certificate for the server. The SSLStatus event provides information about the DTLS handshake. When client authentication is required, the SSLAuthenticateClients property can be set to True and the SSLClientAuthentication event can be used to examine client credentials.

The class provides both encoding/decoding and transport capabilities, making the task of developing a custom SNMP Trap manager as simple as setting a few key properties and handling a few events. SNMP data, such as for instance SNMP object id-s (OID-s) are exchanged as text strings, thus further simplifying the task of handling them.

The class is activated/deactivated by calling the Activate or Deactivate method. These methods enable or disable sending and receiving. The activation status can be found in the Active property.

Messages are received through events such as Trap, InformRequest, or DiscoveryRequest.

SNMP OIDs, types, and values are provided in the Objects collection of SNMP objects for both sent and received packets.

SNMPv3 USM security passwords are requested through the GetUserPassword event, and event parameters such as User and SecurityLevel provide information about the security attributes of received requests, and enable granular decision capability about what to provide and what not to provide.

The AddUser, RemoveUser, ShowCache, ClearCache, AddEngine, and RemoveEngine methods are used to manage an internal authentication cache. This internal cache can be used as an alternative to the GetUserPassword event, automatically checking the cache against the security parameters provided in the request signature.

Unicode (Windows)
BOOL GetAcceptData();
INT SetAcceptData(BOOL bAcceptData);

int ipworkssnmp_snmptrapmgr_getacceptdata(void* lpObj);
int ipworkssnmp_snmptrapmgr_setacceptdata(void* lpObj, int bAcceptData);

bool GetAcceptData();
int SetAcceptData(bool bAcceptData);

Default Value

TRUE

Remarks

Setting the property to False temporarily disables data reception. Setting the property to True re-enables data reception.

This property is not available at design time.

Data Type

Boolean

Active Property (SNMPTrapMgr Class)

Indicates whether the class is active.

Syntax

ANSI (Cross Platform)
int GetActive();
int SetActive(int bActive);

Unicode (Windows)
BOOL GetActive();
INT SetActive(BOOL bActive);

int ipworkssnmp_snmptrapmgr_getactive(void* lpObj);
int ipworkssnmp_snmptrapmgr_setactive(void* lpObj, int bActive);

bool GetActive();
int SetActive(bool bActive);

Default Value

FALSE

Remarks

This property indicates whether the class is currently active and can send or receive data.

The class will be automatically activated if it is not already and you attempt to perform an operation which requires the class to be active.

Use the Activate and Deactivate methods to control whether the class is active.

This property is not available at design time.

Data Type

Boolean

LocalEngineId Property (SNMPTrapMgr Class)

The Engine Id (for SNMPv3).

Syntax

ANSI (Cross Platform)
int GetLocalEngineId(char* &lpLocalEngineId, int &lenLocalEngineId);
int SetLocalEngineId(const char* lpLocalEngineId, int lenLocalEngineId);

Unicode (Windows)
INT GetLocalEngineId(LPSTR &lpLocalEngineId, INT &lenLocalEngineId);
INT SetLocalEngineId(LPCSTR lpLocalEngineId, INT lenLocalEngineId);

int ipworkssnmp_snmptrapmgr_getlocalengineid(void* lpObj, char** lpLocalEngineId, int* lenLocalEngineId);
int ipworkssnmp_snmptrapmgr_setlocalengineid(void* lpObj, const char* lpLocalEngineId, int lenLocalEngineId);

QByteArray GetLocalEngineId();
int SetLocalEngineId(QByteArray qbaLocalEngineId);

Default Value

Remarks

This property is necessary for properly handling InformRequest packets.

Data Type

Binary String

LocalHost Property (SNMPTrapMgr Class)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

ANSI (Cross Platform)
char* GetLocalHost();
int SetLocalHost(const char* lpszLocalHost);

Unicode (Windows)
LPWSTR GetLocalHost();
INT SetLocalHost(LPCWSTR lpszLocalHost);

char* ipworkssnmp_snmptrapmgr_getlocalhost(void* lpObj);
int ipworkssnmp_snmptrapmgr_setlocalhost(void* lpObj, const char* lpszLocalHost);

QString GetLocalHost();
int SetLocalHost(QString qsLocalHost);

Default Value

Remarks

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

Note: LocalHost is not persistent. You must always set it in code, and never in the property window.

Data Type

String

LocalPort Property (SNMPTrapMgr Class)

The port in the local host where the class is bound to.

Syntax

ANSI (Cross Platform)
int GetLocalPort();
int SetLocalPort(int iLocalPort);

Unicode (Windows)
INT GetLocalPort();
INT SetLocalPort(INT iLocalPort);

int ipworkssnmp_snmptrapmgr_getlocalport(void* lpObj);
int ipworkssnmp_snmptrapmgr_setlocalport(void* lpObj, int iLocalPort);

int GetLocalPort();
int SetLocalPort(int iLocalPort);

Default Value

162

Remarks

The LocalPort property must be set before the class is activated (Active is set to True). It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

The default port is 162 (standard trap port). If that port is busy, an error will be returned, unless the ForceLocalPort configuration setting is set to False, in which case a random port will be chosen.

LocalPort cannot be changed once the class is Active. Any attempt to set the LocalPort property when the class is Active will generate an error.

Note: on macOS and iOS, root permissions are required to set LocalPort to any value below 1024.

Data Type

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* ipworkssnmp_snmptrapmgr_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Deactivate Method (SNMPTrapMgr Class)

Deactivates the class.

Syntax

ANSI (Cross Platform)
int Deactivate();

Unicode (Windows)
INT Deactivate();

int ipworkssnmp_snmptrapmgr_deactivate(void* lpObj);

void BadPacket(SNMPTrapMgrBadPacketEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireBadPacket(SNMPTrapMgrBadPacketEventParams *e) {...}

Remarks

The full message is provided in the Packet parameter.

The BadPacket event is also fired when authentication fails for received packets due to a bad password or other reasons.

If the Report parameter is set to True, an unauthenticated error report will be sent to the client, otherwise the packet will be silently ignored.

void CacheEntry(SNMPTrapMgrCacheEntryEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireCacheEntry(SNMPTrapMgrCacheEntryEventParams *e) {...}

Remarks

CacheEntry events are triggered by a call to ShowCache. One event is fired for each user and engine. If there are no users for a particular engine, a single event is fired with the engine information, but empty values for user information.

CheckEngine Event (SNMPTrapMgr Class)

Fired to check engine parameters (timeliness, etc.).

Syntax

ANSI (Cross Platform)
virtual int FireCheckEngine(SNMPTrapMgrCheckEngineEventParams *e);

typedef struct {
  const char *EngineId;
  int lenEngineId;
  int EngineBoots;
  int EngineTime;
  const char *User;
  int SecurityLevel;
  const char *RemoteAddress;
  int RemotePort;
  int IsNew;
  int Accept;
  int reserved;
} SNMPTrapMgrCheckEngineEventParams;


Unicode (Windows)
virtual INT FireCheckEngine(SNMPTrapMgrCheckEngineEventParams *e);

typedef struct {
  LPCSTR EngineId;
  INT lenEngineId;
  INT EngineBoots;
  INT EngineTime;
  LPCWSTR User;
  INT SecurityLevel;
  LPCWSTR RemoteAddress;
  INT RemotePort;
  BOOL IsNew;
  BOOL Accept;
  INT reserved;
} SNMPTrapMgrCheckEngineEventParams;

#define EID_SNMPTRAPMGR_CHECKENGINE 3

virtual INT IPWORKSSNMP_CALL FireCheckEngine(LPSTR &lpEngineId, INT &lenEngineId, INT &iEngineBoots, INT &iEngineTime, LPSTR &lpszUser, INT &iSecurityLevel, LPSTR &lpszRemoteAddress, INT &iRemotePort, BOOL &bIsNew, BOOL &bAccept);

class SNMPTrapMgrCheckEngineEventParams {

};

// To handle, connect one or more slots to this signal.
void CheckEngine(SNMPTrapMgrCheckEngineEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireCheckEngine(SNMPTrapMgrCheckEngineEventParams *e) {...}

Remarks

The Accept parameter determines if the engine will be accepted or not. If you set Accept to False prior to exiting the event, the processing on the message will stop and a BadPacket event will be fired.

The default value of Accept is True if and only if:

a) the engine already exists in the internal authentication cache (the IsNew parameter is False) and the timeliness has been verified;

b) the engine does not exist in the internal authentication cache (the IsNew parameter is True), but the packet has been authenticated by the class (SecurityLevel >= 1).

In all other cases, the default value for Accept is False, and you are responsible for accepting or not accepting the engine based on other considerations.

If Accept is true upon event exit, then:

a) if the engine already exists in the internal authentication cache, its time is updated to reflect the new time and the processing of the packet continues;

b) if the engine does not exist in the internal authentication cache, it is added there and if User is authenticated, the User will be added too.

Connected Event (SNMPTrapMgr Class)

Fired immediately after a connection completes (or fails).

Syntax

ANSI (Cross Platform)
virtual int FireConnected(SNMPTrapMgrConnectedEventParams *e);

typedef struct {
  const char *RemoteAddress;
  int RemotePort;
  int StatusCode;
  const char *Description;
  int reserved;
} SNMPTrapMgrConnectedEventParams;


Unicode (Windows)
virtual INT FireConnected(SNMPTrapMgrConnectedEventParams *e);

};

// To handle, connect one or more slots to this signal.
void Connected(SNMPTrapMgrConnectedEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireConnected(SNMPTrapMgrConnectedEventParams *e) {...}

Remarks

This event fires after a connection completes or fails.

StatusCode is the value returned by the system TCP/IP stack. This will be 0 if the connection was successful.

Description contains a human readable description of the status. This will be "OK" if the connection was successful.

RemoteAddress is the IP address of the remote host.

RemotePort is the port on the remote host.

Disconnected Event (SNMPTrapMgr Class)

Fired when a connection is closed.

Syntax

ANSI (Cross Platform)
virtual int FireDisconnected(SNMPTrapMgrDisconnectedEventParams *e);

typedef struct {
  const char *RemoteAddress;
  int RemotePort;
  int StatusCode;
  const char *Description;
  int reserved;

  INT StatusCode;
  LPCWSTR Description;
  INT reserved;
} SNMPTrapMgrDisconnectedEventParams;

#define EID_SNMPTRAPMGR_DISCONNECTED 5

virtual INT IPWORKSSNMP_CALL FireDisconnected(LPSTR &lpszRemoteAddress, INT &iRemotePort, INT &iStatusCode, LPSTR &lpszDescription);

class SNMPTrapMgrDisconnectedEventParams {
public:
  const QString &RemoteAddress();

  int RemotePort();

  int StatusCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Disconnected(SNMPTrapMgrDisconnectedEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireDisconnected(SNMPTrapMgrDisconnectedEventParams *e) {...}

Remarks

This event fires after a connection is broken.

StatusCode is the value returned by the system TCP/IP stack. This will be 0 if the connection was broken normally.

Description contains a human readable description of the status. This will be "OK" if the connection was broken normally.

RemoteAddress is the IP address of the remote host.

RemotePort is the port on the remote host.

DiscoveryRequest Event (SNMPTrapMgr Class)

Fired when an SNMPv3 discovery packet is received.

Syntax

ANSI (Cross Platform)
virtual int FireDiscoveryRequest(SNMPTrapMgrDiscoveryRequestEventParams *e);

typedef struct {
  const char *EngineId;
  int lenEngineId;
  int EngineBoots;
  int EngineTime;
  const char *User;
  int SecurityLevel;
  const char *SourceAddress;
  int SourcePort;
  int Respond;
  int reserved;
} SNMPTrapMgrDiscoveryRequestEventParams;


Unicode (Windows)
virtual INT FireDiscoveryRequest(SNMPTrapMgrDiscoveryRequestEventParams *e);

typedef struct {
  LPCSTR EngineId;
  INT lenEngineId;
  INT EngineBoots;
  INT EngineTime;
  LPCWSTR User;
  INT SecurityLevel;
  LPCWSTR SourceAddress;
  INT SourcePort;
  BOOL Respond;
  INT reserved;
} SNMPTrapMgrDiscoveryRequestEventParams;

#define EID_SNMPTRAPMGR_DISCOVERYREQUEST 6

virtual INT IPWORKSSNMP_CALL FireDiscoveryRequest(LPSTR &lpEngineId, INT &lenEngineId, INT &iEngineBoots, INT &iEngineTime, LPSTR &lpszUser, INT &iSecurityLevel, LPSTR &lpszSourceAddress, INT &iSourcePort, BOOL &bRespond);

class SNMPTrapMgrDiscoveryRequestEventParams {
public:
  const QByteArray &EngineId();

  int EngineBoots();

  int EngineTime();

  const QString &User();

  int SecurityLevel();

  const QString &SourceAddress();

  int SourcePort();

  bool Respond();
  void SetRespond(bool bRespond);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void DiscoveryRequest(SNMPTrapMgrDiscoveryRequestEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireDiscoveryRequest(SNMPTrapMgrDiscoveryRequestEventParams *e) {...}

Remarks

EngineId, EngineBoots, EngineTime, and User are the values received from SourceAddress.

For SNMPv3, the User parameter shows the user that was supplied with the packet. This parameter MUST be used together with the SecurityLevel parameter which shows the level of security in the message.

The SecurityLevel parameter shows whether the request has been authenticated. If SecurityLevel is 0, the request has NOT been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, SecurityLevel is 1. For an authenticated and encrypted request, SecurityLevel is 2.

Respond is True by default, and will automatically send a response using the value in LocalEngineId. To suppress the response, set Respond to False.

The value returned to SourceAddress for EngineBoots is always 0, and EngineTime is the number of seconds since January 1st, 1970 (GMT).

Error Event (SNMPTrapMgr Class)

Fired when information is available about errors during data delivery.

Syntax

ANSI (Cross Platform)
virtual int FireError(SNMPTrapMgrErrorEventParams *e);

typedef struct {
  int ErrorCode;
  const char *Description;
  int reserved;
} SNMPTrapMgrErrorEventParams;


Unicode (Windows)
virtual INT FireError(SNMPTrapMgrErrorEventParams *e);

typedef struct {
  INT ErrorCode;
  LPCWSTR Description;
  INT reserved;
} SNMPTrapMgrErrorEventParams;

#define EID_SNMPTRAPMGR_ERROR 7

virtual INT IPWORKSSNMP_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);

class SNMPTrapMgrErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Error(SNMPTrapMgrErrorEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireError(SNMPTrapMgrErrorEventParams *e) {...}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

GetUserPassword Event (SNMPTrapMgr Class)

Retrieves a password associated with a user.

Syntax

ANSI (Cross Platform)
virtual int FireGetUserPassword(SNMPTrapMgrGetUserPasswordEventParams *e);

typedef struct {
  int PasswordType;
  const char *User;
  const char *EngineId;
  int lenEngineId;
  char *Password;
  int Algorithm;
  int reserved;
} SNMPTrapMgrGetUserPasswordEventParams;


Unicode (Windows)
virtual INT FireGetUserPassword(SNMPTrapMgrGetUserPasswordEventParams *e);

typedef struct {
  INT PasswordType;
  LPCWSTR User;
  LPCSTR EngineId;
  INT lenEngineId;
  LPWSTR Password;
  INT Algorithm;
  INT reserved;
} SNMPTrapMgrGetUserPasswordEventParams;

#define EID_SNMPTRAPMGR_GETUSERPASSWORD 8

virtual INT IPWORKSSNMP_CALL FireGetUserPassword(INT &iPasswordType, LPSTR &lpszUser, LPSTR &lpEngineId, INT &lenEngineId, LPSTR &lpszPassword, INT &iAlgorithm);

class SNMPTrapMgrGetUserPasswordEventParams {
public:
  int PasswordType();

  const QString &User();

  const QByteArray &EngineId();

  const QString &Password();
  void SetPassword(const QString &qsPassword);

  int Algorithm();
  void SetAlgorithm(int iAlgorithm);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void GetUserPassword(SNMPTrapMgrGetUserPasswordEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireGetUserPassword(SNMPTrapMgrGetUserPasswordEventParams *e) {...}

Remarks

The GetUserPassword event is fired after initial inspection of SNMPv3 requests.

The type of password required is provided in the PasswordType parameter: 1 for authentication, and 2 for encryption (privacy).

The password corresponding to User and EngineId must be provided in the Password parameter. If the password is valid, processing will continue to other events such as GetRequest, SetRequest, etc.

If the PasswordType parameter is 1 (authentication is used), the Algorithm parameter can be set. Possible values are:


Value	Authentication Algorithm
0 (default)	Any
1	MD5
2	SHA1
3	SHA256
4	SHA512

If the PasswordType parameter is 2 (encryption is used), the Algorithm parameter must also be set. Possible values are:


Value	Encryption Algorithm
1 (default)	DES
2	AES
3	3DES
4	AES192
5	AES256

If the password does not match the signature in the request, a BadPacket event will be fired, at which point you can decide whether to report the error to the client (see the description of the BadPacket event for more information).

If the User is invalid or unknown, set the password to empty string (default) to ignore the request. This will result in a BadPacket event being fired, at which point you can decide whether to report the error to the client or not.

GetUserSecurityLevel Event (SNMPTrapMgr Class)

Sets the security level for an incoming packet.

Syntax

ANSI (Cross Platform)
virtual int FireGetUserSecurityLevel(SNMPTrapMgrGetUserSecurityLevelEventParams *e);

typedef struct {
  const char *User;
  const char *EngineId;
  int lenEngineId;
  int SecurityLevel;
  int reserved;
} SNMPTrapMgrGetUserSecurityLevelEventParams;


Unicode (Windows)
virtual INT FireGetUserSecurityLevel(SNMPTrapMgrGetUserSecurityLevelEventParams *e);

typedef struct {
  LPCWSTR User;
  LPCSTR EngineId;
  INT lenEngineId;
  INT SecurityLevel;
  INT reserved;
} SNMPTrapMgrGetUserSecurityLevelEventParams;

#define EID_SNMPTRAPMGR_GETUSERSECURITYLEVEL 9

virtual INT IPWORKSSNMP_CALL FireGetUserSecurityLevel(LPSTR &lpszUser, LPSTR &lpEngineId, INT &lenEngineId, INT &iSecurityLevel);

class SNMPTrapMgrGetUserSecurityLevelEventParams {
public:
  const QString &User();

  const QByteArray &EngineId();

  int SecurityLevel();
  void SetSecurityLevel(int iSecurityLevel);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void GetUserSecurityLevel(SNMPTrapMgrGetUserSecurityLevelEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireGetUserSecurityLevel(SNMPTrapMgrGetUserSecurityLevelEventParams *e) {...}

Remarks

The GetUserSecurityLevel event is fired after the first inspection of each SNMPv3 request. The SecurityLevel parameter determines the level of security for the message.

On entry, the SecurityLevel parameter contains the default security level for User if the user is located in the internal cache, or if the User is not found in the cache, the SecurityLevel will be -1.

The value of SecurityLevel upon exiting the event, determines how the message will be processed:


-1	The message will be ignored and a BadPacket event will be fired.
0	No security. The message will be processed without any authentication and/or encryption.
1	Authentication only. The message will be checked for a valid signature and the GetUserPassword event will be fired to verify the authentication password.
2	Authentication and Privacy. The message will be checked for a valid signature and the GetUserPassword event will be fired twice: first to verify the authentication password, and then to verify the privacy password.

HashPassword Event (SNMPTrapMgr Class)

Fired before and after a password is hashed.

Syntax

ANSI (Cross Platform)
virtual int FireHashPassword(SNMPTrapMgrHashPasswordEventParams *e);

typedef struct {
  const char *Password;
  int AuthAlgorithm;
  char *Hash;
  int reserved;
} SNMPTrapMgrHashPasswordEventParams;


Unicode (Windows)
virtual INT FireHashPassword(SNMPTrapMgrHashPasswordEventParams *e);

typedef struct {
  LPCWSTR Password;
  INT AuthAlgorithm;
  LPWSTR Hash;
  INT reserved;
} SNMPTrapMgrHashPasswordEventParams;

#define EID_SNMPTRAPMGR_HASHPASSWORD 10

virtual INT IPWORKSSNMP_CALL FireHashPassword(LPSTR &lpszPassword, INT &iAuthAlgorithm, LPSTR &lpszHash);

class SNMPTrapMgrHashPasswordEventParams {
public:
  const QString &Password();

  int AuthAlgorithm();

  const QString &Hash();
  void SetHash(const QString &qsHash);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void HashPassword(SNMPTrapMgrHashPasswordEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireHashPassword(SNMPTrapMgrHashPasswordEventParams *e) {...}

Remarks

SNMPv3 passwords are hashed in order to obtain authentication and encryption keys. This is an expensive operation, and in certain situations it may be preferable to store the hashed passwords externally and supply them on demand.

If a hash is required, the event fires with an empty string in the Hash parameter. In this case, you can choose to supply a value for the hash and stop the class from computing the hash.

The event also fires every time a hash is computed. In this case, the Hash parameter contains the value of the computed hash.

AuthAlgorithm contains either 1 for HMAC-MD5-96, 2 for HMAC-SHA-96 or 3 for HMAC-192-SHA-256

InformRequest Event (SNMPTrapMgr Class)

Fired when an InformRequest packet is received.

Syntax

ANSI (Cross Platform)
virtual int FireInformRequest(SNMPTrapMgrInformRequestEventParams *e);

typedef struct {
  int RequestId;
  int SNMPVersion;
  const char *Community;
  const char *User;
  int SecurityLevel;
  const char *SourceAddress;
  int SourcePort;
  int ErrorIndex;
  int ErrorStatus;
  const char *ErrorDescription;
  int Respond;
  int reserved;
} SNMPTrapMgrInformRequestEventParams;


Unicode (Windows)
virtual INT FireInformRequest(SNMPTrapMgrInformRequestEventParams *e);

typedef struct {
  INT RequestId;
  INT SNMPVersion;
  LPCWSTR Community;
  LPCWSTR User;
  INT SecurityLevel;
  LPCWSTR SourceAddress;
  INT SourcePort;
  INT ErrorIndex;
  INT ErrorStatus;
  LPCWSTR ErrorDescription;
  BOOL Respond;
  INT reserved;
} SNMPTrapMgrInformRequestEventParams;

#define EID_SNMPTRAPMGR_INFORMREQUEST 11

virtual INT IPWORKSSNMP_CALL FireInformRequest(INT &iRequestId, INT &iSNMPVersion, LPSTR &lpszCommunity, LPSTR &lpszUser, INT &iSecurityLevel, LPSTR &lpszSourceAddress, INT &iSourcePort, INT &iErrorIndex, INT &iErrorStatus, LPSTR &lpszErrorDescription, BOOL &bRespond);

class SNMPTrapMgrInformRequestEventParams {
public:
  int RequestId();

  int SNMPVersion();

  const QString &Community();

  const QString &User();

  int SecurityLevel();

  const QString &SourceAddress();

  int SourcePort();

  int ErrorIndex();
  void SetErrorIndex(int iErrorIndex);

  int ErrorStatus();
  void SetErrorStatus(int iErrorStatus);

  const QString &ErrorDescription();

  bool Respond();
  void SetRespond(bool bRespond);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void InformRequest(SNMPTrapMgrInformRequestEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireInformRequest(SNMPTrapMgrInformRequestEventParams *e) {...}

Remarks

The user in an InformRequest packet (SNMPv3) must be a valid user in the internal authentication cache (see the AddUser method and the CheckEngine event for more information). If not, the request is rejected, and a BadPacket event is fired before InformRequest is fired.

The list of variables in the SNMP packet, including optional values and types, is provided through the Objects collection. Each object is of type SNMPObject. This type describes the Oid, ObjectType, and Value of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events.

The SourceAddress and SourcePort parameters show the address and port of the sender as reported by the TCP/IP stack.

The MessageId parameter identifies the received request.

To send a response, the Respond parameter must be set to true. By default, this value is false, which means no response will be sent. The ErrorStatus parameter may also be set to a valid SNMP status code (the default value is 0, which represents no error).

The following is a list of valid SNMP status code values:


0 (noError)	No error.
1 (tooBig)	The response cannot fit in a single SNMP message.
2 (noSuchName)	Variable does not exist.
3 (badValue)	Invalid value or syntax.
4 (readOnly)	Variable is read-only.
5 (genError)	Other error (SNMPv1).
6 (noAccess)	Access denied.
7 (wrongType)	Wrong object type.
8 (wrongLength)	Wrong length.
9 (wrongEncoding)	Wrong encoding.
10 (wrongValue)	Wrong value.
11 (noCreation)	No creation.
12 (inconsistentValue)	Inconsistent value.
13 (resourceUnavailable)	Resource unavailable.
14 (commitFailed)	Commit failed.
15 (undoFailed)	Undo failed.
16 (authorizationError)	Authorization error.
17 (notWritable)	Variable is not writable.
18 (inconsistentName)	Inconsistent name.

The ErrorIndex parameter indicates the index of the first variable (object) that caused an error. The default value is 0.

Variable indexes start with 0. ErrorIndex has no meaning when ErrorStatus is 0 (no error).

PacketTrace Event (SNMPTrapMgr Class)

Fired for every packet sent or received.

Syntax

ANSI (Cross Platform)
virtual int FirePacketTrace(SNMPTrapMgrPacketTraceEventParams *e);

typedef struct {
  const char *Packet;
  int lenPacket;
  int Direction;
  const char *PacketAddress;
  int PacketPort;
  int reserved;
} SNMPTrapMgrPacketTraceEventParams;


Unicode (Windows)
virtual INT FirePacketTrace(SNMPTrapMgrPacketTraceEventParams *e);

typedef struct {
  LPCSTR Packet;
  INT lenPacket;
  INT Direction;
  LPCWSTR PacketAddress;
  INT PacketPort;
  INT reserved;
} SNMPTrapMgrPacketTraceEventParams;

#define EID_SNMPTRAPMGR_PACKETTRACE 12

virtual INT IPWORKSSNMP_CALL FirePacketTrace(LPSTR &lpPacket, INT &lenPacket, INT &iDirection, LPSTR &lpszPacketAddress, INT &iPacketPort);

class SNMPTrapMgrPacketTraceEventParams {
public:
  const QByteArray &Packet();

  int Direction();

  const QString &PacketAddress();

  int PacketPort();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void PacketTrace(SNMPTrapMgrPacketTraceEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FirePacketTrace(SNMPTrapMgrPacketTraceEventParams *e) {...}

Remarks

The PacketTrace event shows all the packets sent or received by the class.

Packet contains the full contents of the datagram.

Direction shows the direction of the packet: 1 for incoming packets, and 2 for outgoing packets.

In the case of an incoming packet, PacketAddress and PacketPort identify the source of the packet.

In the case of an outgoing packet, PacketAddress and PacketPort identify the destination of the packet.

SSLClientAuthentication Event (SNMPTrapMgr Class)

Fired when the client presents its credentials to the server.

Syntax

ANSI (Cross Platform)
virtual int FireSSLClientAuthentication(SNMPTrapMgrSSLClientAuthenticationEventParams *e);

typedef struct {
  const char *RemoteAddress;
  int RemotePort;
  const char *CertEncoded;
  int lenCertEncoded;
  const char *CertSubject;
  const char *CertIssuer;
  const char *Status;
  int Accept;
  int reserved;
} SNMPTrapMgrSSLClientAuthenticationEventParams;


Unicode (Windows)
virtual INT FireSSLClientAuthentication(SNMPTrapMgrSSLClientAuthenticationEventParams *e);

typedef struct {
  LPCWSTR RemoteAddress;
  INT RemotePort;
  LPCSTR CertEncoded;
  INT lenCertEncoded;
  LPCWSTR CertSubject;
  LPCWSTR CertIssuer;
  LPCWSTR Status;
  BOOL Accept;
  INT reserved;
} SNMPTrapMgrSSLClientAuthenticationEventParams;

#define EID_SNMPTRAPMGR_SSLCLIENTAUTHENTICATION 13

virtual INT IPWORKSSNMP_CALL FireSSLClientAuthentication(LPSTR &lpszRemoteAddress, INT &iRemotePort, LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);

class SNMPTrapMgrSSLClientAuthenticationEventParams {
public:
  const QString &RemoteAddress();

  int RemotePort();

  const QByteArray &CertEncoded();

  const QString &CertSubject();

  const QString &CertIssuer();

  const QString &Status();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSLClientAuthentication(SNMPTrapMgrSSLClientAuthenticationEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireSSLClientAuthentication(SNMPTrapMgrSSLClientAuthenticationEventParams *e) {...}

Remarks

This event fires when a client connects to the class and presents a certificate for authentication. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK").

// To handle, connect one or more slots to this signal.
void Trap(SNMPTrapMgrTrapEventParams *e);

// Or, subclass SNMPTrapMgr and override this emitter function.
virtual int FireTrap(SNMPTrapMgrTrapEventParams *e) {...}

Remarks

The TrapOID and TimeStamp parameters contain the Trap OID and TimeStamp. In the case of an SNMPv1 trap, there are two possible scenarios:

First, if the enterprise of the trap is "1.3.6.1.6.3.1.1.5", TrapOID will be a concatenation of TrapEnterprise and GenericTrap + 1. For instance a TrapOID of "1.3.6.1.6.3.1.1.5.5" has a TrapEnterprise of "1.3.6.1.6.3.1.1.5" and a GenericTrap of "4".

Second, In all other cases TrapOID will be a concatenation of the values for TrapEnterprise, GenericTrap, and SpecificTrap, separated by '.'.

For SNMPv2 and above, they are read from the variable-value list (if available).

The SourceAddress and SourcePort parameters show the address and port of the sender as reported by the TCP/IP stack.

Some parameters are only applicable depending on the SNMPVersion value. The table below shows which parameters are applicable to which SNMP versions.


	SNMPv1	SNMPv2	SNMPv3
AgentAddress	X
Community	X	X
RequestId		X	X
SecurityLevel			X
User			X
SNMPVersion	X	X	X
SourceAddress	X	X	X
SourcePort	X	X	X
TimeStamp	X	X	X
TrapOID	X	X	X

Store
char*
Default Value: "MY"

The name of the certificate store for the client certificate.

The StoreType field denotes the type of the certificate store specified by Store. If the store is password-protected, specify the password in StorePassword.

Store is used in conjunction with the Subject field to specify client certificates. If Store has a value, and Subject or Encoded is set, a search for a certificate is initiated. Please see the Subject field for details.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:


MY	A certificate store holding personal certificates with their associated private keys.
CA	Certifying authority certificates.
ROOT	Root certificates.

When the certificate store type is cstPFXFile, this property must be set to the name of the file. When the type is cstPFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

StorePassword
char*
Default Value: ""

If the type of certificate store requires a password, this field is used to specify the password needed to open the certificate store.

StoreType
int
Default Value: 0

The type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used, the class will automatically determine the type. This field can take one of the following values:


0 (cstUser - default)	For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: This store type is not available in Java.
1 (cstMachine)	For Windows, this specifies that the certificate store is a machine store. Note: This store type is not available in Java.
2 (cstPFXFile)	The certificate store is the name of a PFX (PKCS#12) file containing certificates.
3 (cstPFXBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format.
4 (cstJKSFile)	The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: This store type is only available in Java.
5 (cstJKSBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: This store type is only available in Java.

23 (cstPKCS11)	The certificate is present on a physical security key accessible via a PKCS#11 interface. To use a security key, the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to `cstPKCS11`, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's `CertEncoded` parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the Store and set StorePassword to the PIN. Code Example. SSH Authentication with Security Key: `certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);`
99 (cstAuto)	The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Default Value: ""

The certificate's version number. The possible values are the strings "V1", "V2", and "V3".

Subject
char*
Default Value: ""

The subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the field is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

Constructors

Certificate()

Creates a instance whose properties can be set. This is useful for use with when generating new certificates.

Certificate(const char* lpEncoded, int lenEncoded)

Parses Encoded as an X.509 public key.

Certificate(int iStoreType, const char* lpStore, int lenStore, const char* lpszStorePassword, const char* lpszSubject)

StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a byte array containing the certificate data. StorePassword is the password used to protect the store.

After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.

SNMPObject Type

The current SNMP object.

Syntax

IPWorksSNMPSNMPObject (declared in ipworkssnmp.h)

Remarks

This type defines an SNMP object. Each object has an Oid, ObjectType, and Value. These values are populated by the class when incoming packets are received. You may use these fields to define objects to be used in outgoing packets.

The following fields are available:

Fields

ObjectType

SNMPObject(const char* lpszOid, const char* lpValue, int lenValue, int iObjectType)

IPWorksSNMPList Type

Syntax

IPWorksSNMPList<T> (declared in ipworkssnmp.h)

Remarks

IPWorksSNMPList is a generic class that is used to hold a collection of objects of type T, where T is one of the custom types supported by the SNMPTrapMgr class.

Methods

GetCount	This method returns the current size of the collection. int GetCount() {}
SetCount	This method sets the size of the collection. This method returns `0` if setting the size was successful; or `-1` if the collection is `ReadOnly`. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection. int SetCount(int count) {}
Get	This method gets the item at the specified position. The `index` parameter specifies the index of the item in the collection. This method returns `NULL` if an invalid `index` is specified. T* Get(int index) {}
Set	This method sets the item at the specified position. The `index` parameter specifies the index of the item in the collection that is being set. This method returns `-1` if an invalid `index` is specified. Note: Objects created using the `new` operator must be freed using the `delete` operator; they will not be automatically freed by the class. T* Set(int index, T* value) {}

Config Settings (SNMPTrapMgr Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

SNMPTrapMgr Config Settings

AuthenticationKey: The key to use for authentication.

This setting takes the hex-encoded key for authentication and may be set inside GetUserPassword.

CompatibilityMode: Whether to operate the component in a specific compatibility mode.

This setting will cause the component to operate in a manner different than normal so that it is compatible with third-party products and libraries. The following table lists the possible values for this setting:


0 (default)	Component operates normally for greatest compatibility.
1	Component uses SNMP4j-compatible encryption (AES192 and AES256).
2	Component automatically detects whether to use SNMP4j-compatible encryption (AES192 and AES256). Note: This option is only applicable when receiving packets. If you are using SNMPMgr or sending secure traps, you will need to select either 0 or 1.

ContextEngineId: Sets the context engine id of the SNMP entity.

If set, the context engine id included in the PDU will be set.

ContextName: Sets the context name of the SNMP entity.

If set, the context name included in the PDU will be set.

DecryptLogPackets: Whether to decrypt logged packets.

When set to true this setting will cause the class to decrypt packets logged in PacketTrace. This only applies when using SNMP Version 3. The default is false.

EncryptionKey: The key to use for encryption.

This setting takes the hex-encoded key for encryption and may be set inside GetUserPassword.

ForceLocalPort: Forces the class to bind to a specific port.

The default value is True, which makes the class throw an error if LocalPort is busy. When ForceLocalPort is set to False and the port is busy, the class silently chooses another random port.

IncomingContextEngineId: The engine Id of the received packet.

This setting holds the engine Id of the received packet. This may be queried at any time, including from within an event, and returns the engine Id of the received packet. This is not needed in most cases, but can be used to store the incoming engine Id to send an asynchronous response later. This value is read-only.

IncomingContextName: The context name of the received packet.

This setting holds the context name of the received packet. This may be queried at any time, including from within an event, and returns the context name of the received packet. This is not needed in most cases, but can be used to store the incoming context name to send an asynchronous response later. This value is read-only.

ShowCacheForUser: Shows the cache entry for a single user.

This configuration setting causes the class to call ShowCache internally, and only fire the CacheEntry event for the user specified.

SourceAddress: The source address of the received packet.

This setting holds the source address of the received packet. This may be queried at any time, including from within an event, and returns the source address of the received packet. This value is read-only.

SourcePort: The source port of the received packet.

This setting holds the source port of the received packet. This may be queried at any time, including from within an event, and returns the source port of the received packet. This value is read-only.

TimeWindow: The time window used for SNMPv3 timeliness checking (authentication).

The default value is 150 (seconds).

UDP Config Settings

CaptureIPPacketInfo: Used to capture the packet information.

If this is set to True, the component will capture the IP packet information.

The default value for this setting is False.

Note: This configuration setting is available only in Windows.

DelayHostResolution: Whether the hostname is resolved when RemoteHost is set.

This configuration setting specifies whether a hostname is resolved immediately when RemoteHost is set. If true the class will resolve the hostname and the IP address will be present in the RemoteHost property. If false, the hostname is not resolved until needed by the component when a method to connect or send data is called. If desired, ResolveRemoteHost may be called to manually resolve the value in RemoteHost at any time.

The default value is false.

DestinationAddress: Used to get the destination address from the packet information.

If CaptureIPPacketInfo is set to True, then this will be populated with the packet's destination address when a packet is received. This information will be accessible in the DataIn event.

Note: This configuration setting is available only in Windows.

DontFragment: Used to set the Don't Fragment flag of outgoing packets.

When set to True, packets sent by the class will have the Don't Fragment flag set. The default value is False.

LocalHost: The name of the local host through which connections are initiated or accepted.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

LocalPort: The port in the local host where the class binds.

This configuration setting must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxPacketSize: The maximum length of the packets that can be received.

This configuration setting specifies the maximum size of the datagrams that the class will accept without truncation.

QOSDSCPValue: Used to specify an arbitrary QOS/DSCP setting (optional).

UseConnection must be True to use this configuration setting. This option allows you to specify an arbitrary DSCP value between 0 and 63. The default is 0. When set to the default value, the component will not set a DSCP value.

Note: This configuration setting uses the qWAVE API and is available only on Windows 7, Windows Server 2008 R2, and later.

QOSTrafficType: Used to specify QOS/DSCP settings (optional).

UseConnection must be True to use this setting. You may specify either the text or integer values: BestEffort (0), Background (1), ExcellentEffort (2), AudioVideo (3), Voice (4), and Control (5).

Note: This configuration setting uses the qWAVE API and is available only on Windows Vista and Windows Server 2008 or above.

Note: QOSTrafficType must be set before setting Active to True.

ShareLocalPort: If set to True, allows more than one instance of the class to be active on the same local port.

This option must be set before the class is activated through the Active property or it will have no effect.

The default value for this setting is False.

SourceIPAddress: Used to set the source IP address used when sending a packet.

This configuration setting can be used to override the source IP address when sending a packet.

Note: This configuration setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility).

SourceMacAddress: Used to set the source MAC address used when sending a packet.

This configuration setting can be used to override the source MAC address when sending a packet.

Note: This configuration setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility).

UseConnection: Determines whether to use a connected socket.

UseConnection specifies whether or not the class should use a connected socket. The connection is defined as an association in between the local address/port and the remote address/port. As such, this is not a connection in the traditional Transmission Control Protocol (TCP) sense. It means only that the class will send and receive data to and from the specified destination.

The default value for this setting is False.

UseIPv6: Whether or not to use IPv6.

By default, the component expects an IPv4 address for local and remote host properties, and it will create an IPv4 socket. To use IPv6 instead, set this to True.

Socket Config Settings

AbsoluteTimeout: Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method that does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for User Datagram Protocol (UDP) ports.

FirewallData: Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes).

InBufferSize: The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the InBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize: The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the OutBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Config Settings

BuildInfo: Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage: The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo: Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

Product: The product the license is for.
Product Key: The key the license was generated from.
License Source: Where the license was found (e.g., RuntimeLicense, License File).
License Type: The type of license installed (e.g., Royalty Free, Single Server).
Last Valid Build: The last valid build number for which the license will work.

MaskSensitiveData: Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents: Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis: The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseInternalSecurityAPI: Whether or not to use the system security libraries or an internal implementation.

When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
